Step-by-step explanation:
In similar polygons, corresponding sides are in same proportion
Cross multiply
7*(4x-3)=3*(x+1)
28x - 21 = 3x + 3
28x - 3x - 21 = 3
25x = 3 + 21
25x = 24
x = 24/25
x = 0.96
Scale factor = 7 : 3
There are 4 units between points A and B. There are 6 units between points B and C. Since the three points form a right triangle, we can use the Pythagorean Theorem to find the distance between points A and C. The Pythagorean Theorem is:
For this problem, we say the length AC is equal to the square root of AB squared plus BC squared. Since AB is 4 units and BC is 6 units, we can say that
Which is
Which simplifies to
Therefore, the answer is C) root 52
